Description
Technical field
The invention belongs to a kind of insulation fin construction, be specifically related to a kind of insulation fin construction that is used for single-phase DC brushless motor stator winding.
Background technology
Usually, monophase machine is as the drive source of most of household electrical appliance such as compressor, washing machine, electric fan.Because brshless DC motor has replaced brush and commutator with electron rectifier, so it had both had the simple in structure, reliable, easy to maintenance of alternating current machine, possess the operational efficiency height of direct current machine, no excitation loss and good speed adjustment features again, can avoid again producing plurality of advantages such as mechanicalness noise and electromagnetic noise, be widely used in comprising the national economy every field of household electrical appliance.
Motor mainly is made of stator and rotor two parts, and stator has independently loop construction, and permanent-magnet steel is arranged in the rotor.Stator and rotor are made of the iron core that silicon steel plate stacking forms respectively.It is cylindric that stator is, and circle upwards is provided with groove in it.Rotor is cylindric, and rotor directly is pressed on the bent axle and inserts in the stator cylinder cavity, and certain space is arranged between stator and rotor.Stator has the winding of high strength enamelled wire coiled, and stator winding is connected with external power, outside source current by the time this electric current and the rotor permanent-magnet steel magnetic field interaction that produced, produce electromagnetic torque and drive the rotor rotation.
Stator winding is by constituting as the main winding of running winding with as the auxiliary winding that starts winding, winding is to insert an end of coil on the circle in two grooves in a plurality of grooves and insert the other end in stator in other two grooves, is wound with a plurality of windings in stator core.Therefore, be provided with the upper and lower of winding in the top and bottom of stator core, and be fixed with the top and bottom of fixed part in stator core.
That is, winding is divided into the upper end winding that is provided with on periphery unshakable in one's determination, and the lower end winding that is provided with below periphery unshakable in one's determination and be inserted between a plurality of grooves and connect the winding that is connected of upper end winding and lower end winding.
In order to prevent short circuit between the major-minor winding, burn out motor, between the major-minor winding, to separate with insulating material.What generally adopt is that main winding and auxiliary winding are insulated with insulating trip respectively.
As shown in Figure 1, 2, the tubular that stator 1 is formed by a plurality of silicon steel plate stackings, the insulating trip that prior art adopts plastics to make separates the major-minor winding coil and insulate, insulating trip by last slice 2, sheet 4 and intercell connector 3 three parts are formed down, last slice, descend sheet and intercell connector plastic production.Two intercell connectors 3 respectively with last slice 2, sheet 4 forms one in pad 5 welding down, it can be simultaneously separates the major-minor winding coil of stator upper end and lower end and forms insulation like this.
During use, can be after having twined all main windings, twine remaining auxiliary winding coil again after inserting insulating trip, after also two winding coils all can having been twined, again insulating trip is inserted in the slit in the middle of two groups of winding coils, the major-minor winding coil of stator upper and lower end is insulated.Has certain thickness rigid plastics owing to adopt, so insulating trip has certain intensity.
But, there is following problem in the insulation fin construction of prior art, the separate unit motor need use 2 insulating trips, need insert twice during manual operation, the interphase insulating sheet edge upwarps easily after the expense of taking a lot of work material and the shaping, cause defective insulation between the main winding and auxiliary winding, product quality is difficult for guaranteeing that production efficiency descends.
Summary of the invention
Problems of the prior art propose in order to solve in the present invention, and purpose provides a kind of insulation fin construction of monophase machine stator winding of simple in structure, labor and material saving.Technical scheme of the present invention is: a kind of insulation fin construction of monophase machine stator winding, comprise slice, time sheet and intercell connector, last slice be two fan-shaped shapes that connect together, following sheet is two fan-shaped shapes that connect together, last slice and following sheet between link together with intercell connector.
Respectively form an arcuate indentation in the middle of two of last fan-shaped bottoms, its lower end is formed with breach at weld; Respectively form an arcuate indentation in the middle of two of following sheet fan-shaped tops, its upper end is formed with breach at weld.Last slice and following sheet between weld together with 3 intercell connectors.
Insulation fin construction of the present invention, owing to be retrofit into a slice with two, the end of 2 interphase insulating sheets is no longer cut, saved operation, intercell connector also is kept to 3 by original 4, has saved material, has overcome the shortcoming that upwarps the defective insulation that causes because of the edge simultaneously, reduce percent defective, improved production efficiency.

Embodiment
With embodiment the insulation fin construction of monophase machine stator winding of the present invention is elaborated with reference to the accompanying drawings:
Shown in Fig. 3,4, insulating trip of the present invention by last slice 6, sheet 7 and intercell connector 8 constitute down.Last slice 6 be two fan-shaped shapes that connect together, in the middle of its underpart, respectively form an arcuate indentation 10, its lower end is jagged at weld.Following sheet 7 also is two fan-shaped, as to connect together shapes, and the centre respectively forms an arcuate indentation 10 at an upper portion thereof, and its upper end is jagged at weld.Last slice 6, the arcuate indentation of sheet 7 is staggered relatively down, last slice, down between the sheet with 8 connections of three intercell connectors, the cross section of intercell connector 8 is circle or rectangle.Insulating trip last slice, down sheet and intercell connector plastic production, have certain thickness.During making, at first with last slice, down sheet and intercell connector moulding respectively earlier, then with three intercell connectors 8 with last slice 6, sheet 7 links together down, in pad 9 firm welding, at last with insulating trip disposable be inserted into to form between the major-minor winding coil insulate.
Insulation fin construction of the present invention, owing to be retrofit into a slice with two, the end of 2 interphase insulating sheets is no longer cut, saved operation, intercell connector also is kept to 3 by original 4, has saved material, has overcome the shortcoming that upwarps the defective insulation that causes because of the edge simultaneously, reduce percent defective, improved production efficiency.
